When studying underwater acoustic exploration, tracking and positioning, the target signals collected by hydrophones are often submerged in strong intermittent noise environmental noise. In this paper, an algorithm that combines empirical mode decomposition wavelet transform is proposed to achieve efficient extraction of environment with First calibration baseline drift performed on algorithm, ...

Abstract. Developing accurate sea ice drift forecasts is essential to support the decision-making of maritime end-users operating in Arctic. In this study, two calibration methods have been developed for improving 10 d from an operational prediction system (TOPAZ4). The are based on random forest models (supervised machine learning) which were trained using target variables either drifting buoy...

Aiming at the drift problem that tracking control of actual load relative to target during electromagnetic excitation biaxial fatigue test wind turbine blades is easy drift, a testing machine for designed, and following strategy studied. A Fast Transversal Recursive Least Squares algorithm based on fuzzy logic (Fuzzy FTRLS) proposed develop loading dynamic strategy, which adjusts forgetting fac...

— The research community in wireless systems hold a keen interest in sensor networks issues. Sensor networks are dense wireless networks where information is gathered by sensor elements spread out in an interest area. Wireless sensors applications cover a large eld such as surveillance and security, target tracking, agriculture, health and military purposes. The main de ciency of sensors is the...

Citrus tristeza virus (CTV) outbreaks were detected in Sicily island, Italy for the first time in 2002. To gain insight into the evolutionary forces driving the emergence and phylogeography of these CTV populations, we determined and analyzed the nucleotide sequences of the p20 gene from 108 CTV isolates collected from 2002 to 2009. Bayesian phylogenetic analysis revealed that mild and severe C...

The paper is devoted to upper bounds on run-time of NonElitist Genetic Algorithms until some target subset of solutions is visited for the first time. In particular, we consider the sets of optimal solutions and the sets of local optima as the target subsets. Previously known upper bounds are improved by means of drift analysis. Finally, we propose conditions ensuring that a Non-Elitist Genetic...

The sea wave causes excess resistance which is out of scope of calm water resistance. The total wave force in horizontal plane is divided into “Added Resistance” and “Drift Force”. In this study, based on Gerritsma and Beuckelman[3] hypothesis a computer program has been developed for calculation of added resistance and drift force at various ship speeds and various head...

Abstract Introduction As the prognosis of early-stage breast cancer patients is excellent, prevention radiation-induced toxicity has become crucial. Reduction margins compensating for intrafraction motion reduces non-target dose. We assessed tumor bed throughout APBI treatment fractions and calculated CTV-PTV breathing drift. Methods This prospective clinical trial included treated with on a Cy...

This paper presents a dynamic model of takeovers based on the stock market valuations of merging firms. The model incorporates competition and imperfect information and determines the terms and timing of takeovers by solving option exercise games between bidding and target shareholders. The implications of the model for returns to stockholders are consistent with the available evidence. In addi...
